Distracted and disturbed by oil rig explosions, massive oil spills, feckless oil companies and volcanic ash clouds? Speaking of ash, here’s some good news that maybe escaped the attention it deserves: The Environmental Protection Agency wants to regulate coal ash with new rules that will ensure the “safe disposal and management” of ash produced from coal-fired power plants.
Coal ash is known more formally as coal combustion residuals; it is the byproduct of coal combustion and is disposed in liquid form in large surface impoundments and in solid form at landfills.
The residuals contain contaminants such as mercury, cadmium and arsenic, which are associated with cancer and various other serious health effects. The EPA said its risk assessment and damage cases “demonstrate that, without proper protections, these contaminants can leach into groundwater and can migrate to drinking water sources, posing significant health public concerns.”
